Hello,

New Graflex user here. I inherited a few cameras from my father, the most interesting of which was this Graflex RB Series B. It has a ď22Ē Graphic 120 roll holder back attached. I remember my dad telling me at one point that it was a modification heíd had done by a machinist. His memory seemed a little fuzzy on the subject and I wasnít sure I believed him. Having now started to do a little research, and having inspected the roll holder closely, it does appear to have been modified to fit.

Iím totally new to this camera and canít recall ever seeing my dad use it. Iíve read the instruction manual and I think I have a pretty good grip on how to operate it. The only problem now is that the shutter release lever doesnít seem to be working. Lacking a service manual, I donít think I want to start doing any disassembly on my own, so Iíll be taking it to the nearest repair shop for an estimate.

Also, the light shield card that you pull out before taking an exposure (I donít know the correct name) has the edge broken off, so if it is fully inserted into the roll holder, it is flush with the case and canít be gripped to pull it out. It looks like I can leave it not entirely inserted and have it still do its job, but itís pretty precarious. I guess Iíll need to find or make a replacement for that eventually.

Iíll follow up with some pictures as soon as I can get them uploaded to my site.

Look here https://1drv.ms/f/s!AggQfcczvHGN7QPLzcnfQqi0-7pf and here https://www.pacificrimcamera.com/rl/rlgraflexmisc.htm for user manuals.

The dark slide from a 2x3 Graflex film pack adapter will do for you. FPAs turn up on eBay from time to time.

Yes, I can see what the machinist did.

Thanks for the manual links! Sadly no service manual, but I think Iíll leave that to someone who knows what theyíre doing!

I was able to find a replacement 22 Graphic back on EBay fairly cheap with an intact card insert, so thereís that solved.

OR
ask Mike for a copy of the shutter repair manual
https://www.butkus.org/chinon/graflex/graflex_service_parts/graflex_service_parts.htm

Check that the I / T lever is in the I position for instantaneous exposurers
Use the T position for when the curtain is at the T or O positions.

Thanks!

Yeah, those parts are all working fine. Itís just the shutter release lever on the left side of the body, near the lens, which doesnít seem to work.

Does the mirror go up when you press the shutter release lever?
Does the curtain run down if you pull the M lever back?

Curtain wound to O to 1/8, tension on 1 to 6, shutter release releases mirror, as mirror shaft turns a pin on the I-T lever mounted on the H lever contacts the M lever lifting it releasing the curtain to run down 1 position with the I-T lever in the I position.

Possible causes for failure are the release lever plate improperly installed preventing the release of the mirror; pin on the I-T lever bent or missing; the base of the M lever severely worn preventing it from being lifted high enough to release the curtain; wind plate improperly installed or winding mechanism damaged.

If I have the curtain open and look inside as I move the shutter release lever, the inner catch of that lever does not move at all. I can just barely see the spring wiggling as I manipulate the lever, but no other motion. The inner part looks a bit rusty, so perhaps it is frozen in place. Again, this seems like something I should leave to an experienced repair technician. Iím hoping to get it over to a local tech this week, but I also donít know what it is likely to cost to get it fixed. From what Iíve seen, the going rate for a whole camera on eBay seems to be around $300, so Iíll have to decide how important it is to me to get this particular unit working again. It did belong to my dad, so I have a sentimental attachment and would really like to get it working again.

Best I remember the release lever is a solid shaft from lever to catch with a return spring. The mirror frame is cloth covered for blackout of the image box and may be stuck to the wood frame of the body.

With the curtain at O, I-T lever at T, hold the release lever down while pushing up on the bottom front edge of the mirror.
The mirror frame is aluminum so it will not bend easily especially if even pressure is put across the front lip/edge.

It will likely be after the first of the year before I'm back able to do repairs.

@45PSS:
As far as I could tell, the mirror is moving correctly, but Iíll double check, following your instructions above. Perhaps the shaft of the release lever is also rusted and frozen in place?

I just noticed your location, mid-peninsula, Ca. Youíre on the SF Bay Area peninsula? Thatís where I am too!
